This last one!!!! (Maybe)

Andrew [12]

Answer:

142

Step-by-step explanation:

It said to sort it from least to greatest and you did, so we don't need to worry about that. It said ''<u>find the median of the numbers</u>'', which is 137 and 147. Because there are <em>two numbers</em>, we need to work out <em>the middle number</em> of them two.

We start off <em>finding the difference</em> between them <em>which is 10</em> and the middle number of 10 (5). So we just add 5 to 137 (or subtract 5 from 147) which gives us the answer 142

9:39 PM A truck travels on a highway at a speed of 66 miles per hour. What is the speed of the truck in feet per second? Round y

Paul [167]

Answer:

$96.8\frac{feet}{second}$

Step-by-step explanation:

Remember that

$1\ mile =5,280\ feet$

To convert miles to feet multiply by 5,280

$1\ hour =3,600\ sec$

To convert hours to seconds multiply by 3,600

we have

$66\frac{miles}{hour}$

convert to feet per second

$66\frac{miles}{hour}=66(\frac{5,280}{3,600})=96.8\frac{feet}{second}$

Please help within 30ish minutes I’m be g g in g you

Answer:

x - 2y = - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given 2x + y = 3 ( subtract 2x from both sides )

y = - 2x + 3 ← in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-2}$ = $\frac{1}{2}$ , thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute (5, 4) into the partial equation

4 = $\frac{5}{2}$ + c ⇒ c = $\frac{3}{2}$

y = $\frac{1}{2}$ x + $\frac{3}{2}$ ← in slope- intercept form

Multiply through by 2

2y = x + 3 ( subtract 2y from both sides )

0 = x - 2y + 3 ( subtract 3 from both sides )

- 3 = x - 2y , that is

x - 2y = - 3 ← in standard form

The sum of a number and twenty-six, divided by twelve is equal to seven! <br><br> Please!!

Travka [436]

Answer:

58

Step-by-step explanation:

1. let x be the unknown number

2. make an expression

x + 26/12 = 7/1

3. cross multiply

x +26 × 1 = x + 26

12 × 7 = 84

x + 26 = 84

4. move variables on one side and numbers on other side of the equal sign

x + 26 = 84

- 26 -26

x = 58
